Apparatus for supporting a pool cover

ABSTRACT

An apparatus for supporting a cover member over a pre-selected liquid contained in either a swimming pool, hot tub or whirlpool outdoors during a predetermined time of year to protect the swimming pool, hot tub or whirlpool from damaging cold weather and debris. The apparatus includes at least one support member produced from a predetermined material and having a predetermined shape connected between the pre-selected liquid and a predetermined portion of a bottom surface of the cover member for supporting and elevating at least a portion of such cover member. A support member retainer is engageable with each of the support member and predetermined side wall portions of the swimming pool, hot tub or whirlpool to retain such support member in a substantially central location over the pre-selected liquid contained in such swimming pool, hot tub or whirlpool.

CROSS REFERENCE TO RELATED APPLICATION

This application is closely related to and claims benefit from U.S. Provisional Patent Application Ser. No. 60/693,038 filed on Jun. 23, 2005.

FIELD OF THE INVENTION

The present invention relates, in general, to pool covers used to protect swimming pools and the like during predetermined times of the year and, more particularly, the invention relates to an apparatus used to support and elevate at least a central portion of the pool cover, which helps prevent snow and ice from building up on the pool cover as well as aids in the removal of leaves, branches and other debris gathered on the pool cover.

BACKGROUND OF THE INVENTION

Recreational swimming pools and the like have been in existence for many years. During colder seasons of the year, such as fall and winter, many people cover their swimming pools to protect them. In addition, supporting flotation devices are often used to support and elevate the pool covers. These support devices help to keep snow and ice from building up on the cover and allow for more easy removal of such snow and ice. Harmful debris that can gather on the covers are also more easily removed. Another important benefit of these support devices is that they can help prevent expanding ice from breaking or damaging pool walls.

Unfortunately, these support devices often lose air causing them to collapse and allowing the pool cover to sink into the center of the swimming pool. When this happens, snow and ice, or unwanted debris such as leaves and branches, are allowed to collect in the center of the pool, which can possibly cause damage to the cover or pool itself.

A need exists for a more durable and reliable pool cover support apparatus that will maintain its shape and position substantially in the center of the swimming pool.

SUMMARY OF THE INVENTION

A first aspect of the present invention provides an apparatus that supports a cover member used to cover a pre-selected liquid contained in a swimming pool, a hot tub or a whirlpool outdoors during a predetermined time of year to protect the swimming pool, hot tub or whirlpool from damaging cold weather and debris. The apparatus includes at least one support member produced from a predetermined material and having a predetermined shape. The support member is connected between the pre-selected liquid and a predetermined portion of a bottom surface of the cover member to support and elevate at least a portion of such cover member. The apparatus also includes a support member retainer means that is engageable with each of the support member and predetermined side wall portions of either such swimming pool, hot tub or whirlpool to retain such support member in a substantially central location in the swimming pool, hot tub or whirlpool.

A second aspect of the present invention provides an apparatus for covering either a swimming pool, a hot tub or a whirlpool outdoors during a predetermined time of year to protect the swimming pool, hot tub or whirlpool from damaging cold weather and debris. The apparatus includes a cover member produced from a first predetermined material and having a predetermined shape, a predetermined size, a top surface and a bottom surface for covering a pre-selected liquid contained in such swimming pool, hot tub or whirlpool. The apparatus also includes a cover member retainer means that is engageable with each of the cover member and predetermined side wall portions of the swimming pool, hot tub or whirlpool for retaining such cover member over the pre-selected liquid contained in such swimming pool, hot tub or whirlpool. The apparatus further includes at least one support member produced from a second predetermined material and having a predetermined diameter. The support member is connected between such pre-selected liquid and a predetermined portion of the bottom surface of the cover member for supporting and elevating at least a portion of such cover member. The apparatus still further includes a support member retainer means engageable with each of the support member and predetermined side wall portions of such swimming pool, hot tub or whirlpool for retaining such support member in a substantially central location in the swimming pool, hot tub or whirlpool.

OBJECTS OF THE INVENTION

It is, therefore, one of the primary objects of the present invention to provide an apparatus for supporting a pool cover that is constructed using materials similar to exercise balls which will maintain their shape and hold air longer than pool cover supports currently offered on the market.

Another object of the present invention is to provide an apparatus for supporting a pool cover that maintains its position substantially in the center of the pool.

Still another object of the present invention is to provide an apparatus for supporting a pool cover capable of elevating the pool cover higher than standard pool cover supports.

In addition to the above described objects and advantages of the present invention, various other objects and advantages of the apparatus for supporting a pool cover will become more readily apparent to those persons skilled in such art from the more detailed description, particularly, when such description is taken in conjunction with the attached drawing figures and with the appended claims.
